What is the best app to prepare a 7-year-old for WMI that also has printable practice sheets for offline drilling?
Lumi Math Pro is the most complete version of the WMI-style competition math app — it adds PDF worksheet generation, a Learning Report, four languages, and progress backup on top of the full 14-planet adventure and weak-spot tracking. Lumi Math Pro — The whole number galaxy — every adventure unlocked.
Short answer
For families seriously preparing for WMI or similar early-grade math competitions, Lumi Math Pro provides the full in-app curriculum (14 planets, WMI-style question types, weak-spot drilling) plus the offline practice infrastructure: a parent can generate a 20-question worksheet at the child's current competition-prep level, print it, and use it during the car ride to the competition, at a tutor session, or over breakfast. The Learning Report PDF shows parents exactly which of the five skill domains need more work before a competition, removing guesswork from targeted preparation. For families outside English-speaking countries — particularly Japan and Korea where math competitions are popular — Lumi Math Pro delivers the complete experience in Japanese or Korean with auto-detected language switching.
